PE8_7 Mechanical and manufacturing engineering

PE8_1 Aerospace engineering

ERC 3rd level Code

Research Activities

Residual stress (RS) develops during manufacturing processes as a result of heat and mechanical treatment experienced by the material. Welding process generates RS in welded parts and this could lead to some problems in terms of dimensional stability and structural integrity.
Under working condition, the RS combines with the stress field produced by external loads, changing the distribution of stress and influencing the structural stability and resistance to fatigue and fracture of the structure. The experimental evaluation of the RS (really difficult to predict) is very important for a proper design.
Complete equipment for RS measurement on real welded components are available. We are able to perform measurements on site.

Research Activities

The TRASFORMA laboratory network includes laboratories of the Polytechnic of Bari, the University of Salento and the National Research Council. The network concentrates skills and equipment for the production of components in light metal alloys of complex shape and / or with locally defined thickness and / or strength characteristics. The laboratory network aims to be a valid point of reference for the industrialization of innovative hot forming processes (based on the use of flexible media such as oil and gas), aimed at the production of components in light metal alloys, which represent today one of the most effective methods to meet the need to lighten up many industrial sectors, such as the automotive, aeronautical, sports and electronic sectors. In order to produce components not only of complex shape, but also with specific and local characteristics of thickness or resistance, the network is equipped with measuring equipment and instruments aimed at the study of sheets of different thickness and / or material (TWB) and control of the friction forces at the interface between material and mold (in order to guide the flow of the material in deformation) through a coating with thin films of hard, wear-resistant material with low friction coefficient.

PE8_11 Sustainable design

Research Activities

The strong commitment of Politecnico di Bari towards manufacturing sustainability deploys into
the proactive promotion of social involvement of its students into the sustainability topics. The
long experience on-the-field led to build up a multidisciplinary laboratory for the promotion and
development of manufacturing sustainability both in research and teaching.
The services offered are directed toward students and/or teachers as well as outside Politecnico
(research and third mission) toward manufacturing companies.
The main services are: analysis for optimisation of manufacturing processes and sustainability
improvement in manufacturing and production systems. Labs are oriented to let the student
gain critical skills on recognising, measuring and applying sustainable solutions to different
manufacturing processes.
Strong competences are available on the analysis of complex real production systems, on the use of
advanced methodologies and non-conventional tools for designing and implementing continuous process actions.

Laboratory of Manufacturing Processes by Laser Technologies

ERC 2nd Level Code

ERC 3rd level Code

Research Activities

Since 2007, the Laboratory of Manufacturing processes by Laser Technologies (LLT) of Politecnico
di Bari has been working on Laser Additive Manufacturing processes of metals and on laser
micro-machining.
The laboratory currently houses a Selective Laser Melting (SLM) and a Laser Metal Deposition
machine, able to process metal powders. Both techniques are solid freeform fabrication processes
where 3D parts can be fabricated layer by layer by fusing metal powders with a high energy laser
beam.
SLM machine is equipped with a nanosecond Nd:YAG laser source with a maximum power of 100
W and a scanning head with deflecting mirrors to direct the laser beam over the powder platform.
The laser can operate in both continuous and pulse mode.
In continuous mode, it allows the selective laser sintering and selective laser melting of metal powders; in pulsed mode, it is able to fabricate micro-components by laser ablation, with a pulse
width in the nanosecond range and a repetition rate between 0 and 65kHz. Materials that can be
processed by selective laser melting are mainly steels. On the other hand, it is possible to treat
different materials (steels, titanium alloys, aluminum alloys, ceramics, glass, etc) by means of laser
micro-machining.
LMD machine is characterized by a 5-axis movement system and by an inert chamber that allows
processing several materials including reactive metals such us titanium and aluminum alloys.
LMD is used for solid freeform fabrication and for laser cladding.
The main research topics carried out in the laboratory are:
• Study and characterization of materials obtained by Selective Laser Melting and Selective
Laser Sintering
• Manufacturing of hybrid structures and porous structures with controlled density by Selective
Laser Melting
• Thermal treatments of sintered materials
• Laser surface processing of metals and glass
• Repair of aeronautic components by Laser Metal Deposition
• Freeform fabrication of complex geometries by Selective Laser Melting and Laser Metal
Deposition
• Laser Metal Deposition of WC by Functionally Graded Materials technique
• Development of numerical and analytical models for process optimization

Laboratory of Intelligent Computation for Manufacturing and Production Systems

Research Activities

Simulation models and mathematical programming techniques can deal with manufacturing systems which call for complex decisions concerning daily issues as well as middle and long horizon strategies (e.g. the introduction of new machines, new products, etc.). Among the most recent computing algorithms, artificial and swarm intelligences have demonstrated their capability of solving scheduling, programming, and maintenance problems in manufacturing complex systems.
The team of Laboratory of “Intelligent Computation for Manufacturing and Manufacturing Systems” have matured a considerable experience in resolving optimization problems for advanced technologies like welding and additive fabrication ones, and modelling the overall manufacturing system. The same approach can be potentially applied to a variety of processes that involve low resources availability and necessity of a high degree of efficiency, like processes in the health care systems.
The team can design a screening experiment and explore the process to be simulated by enquire its actors. The information is structured as an input to the process and several solutions are found by means of commercial software and customer programming. Then, they will discuss until the better solution, if not the best, is selected.
The capability of the team embraces also the use of Statistical Process Control (SPC) with the aid of Design of Experiment technique (DoE).
